Abstract
Hybrid matrix fiber composites having enhanced compressive performance as well as enhanced stiffness, toughness and durability suitable for compression-critical applications. The methods for producing the fiber composites using matrix hybridization. The hybrid matrix fiber composites comprised of two chemically or physically bonded matrix materials, whereas the first matrix materials are used to impregnate multi-filament fibers formed into ribbons and the second matrix material is placed around and between the fiber ribbons that are impregnated with the first matrix material and both matrix materials are cured and solidified.
Claims14
A method of producing a hybrid matrix fiber composite from a plurality of fibers and from matrix materials, said method comprising steps:
- (a) aligning said plurality of fibers and impregnating them in a first matrix material to form one or more impregnated ribbons;
- (b) at least partially curing or otherwise solidifying said first matrix material around said aligned fibers to preserve fiber alignment and impart stiffness and compressive strength to the ribbons;
- (c) aligning and embedding said impregnated and at least partially cured ribbons within a second matrix material;
- (d) curing or otherwise solidifying said first and second matrix materials to chemically or physically bond said first and second matrix materials into an integrally bonded hybrid matrix composite.
A method for manufacturing of a hybrid matrix fiber composite, said method comprising:
- (a) producing a plurality of ribbons by:
- i) impregnating fibers comprising filaments in a first matrix material;
- and
- ii) curing the first matrix material by solidifying or semi-solidifying the first matrix material around said fibers to preserve fiber alignment and impart stiffness and compressive strength to the ribbons thus formed;
- (b) distributing said ribbons evenly within a second matrix material;
- and
- (c) curing the first and second matrix material to form chemical or physical bonds between said first matrix material and said second matrix material into a hybrid matrix fiber composite.
